How does one decifer the filenames for textures and icon images in relation to their respective blueprints for TSL? What I mean is I want to make custom items using the blueprints and then find which textures they are linked to. I am confused because it is a long list of class4_002, class4_003, class5 etc. also PMBD09, PMBD10, PMBE01 etc. how do I interpret these? how do I find link them to a blueprint?
